狗狗被蚊子叮咬会得什么病（犬心丝虫病的症状和预防方法）

狗狗被蚊子叮咬容易患上犬心丝虫病，症状包括咳嗽、呼吸急促、食欲不振等，严重时会危及生命。预防方法包括定期给狗狗进行驱蚊和预防犬心丝虫的药物治疗。记得带狗狗定期检查身体健康，及时发现问题并治疗。

​夏天各种飞行动物都出来打扰人类以及宠物们，如：苍蝇、寄生虫、蚊子等等，当人们被蚊虫叮咬后会不自觉的去拍打它，而狗狗被蚊虫叮咬后，他们却无从下手，如果是住在室外的狗狗那就更惨了。

In summer, all kinds of flying animals come out to disturb people and pets, such as flies, parasites, mosquitoes and so on. When people are bitten by mosquitoes, they will involuntarily swat it, while dogs are bitten by mosquitoes, they have no way to start, if it is the dog that lives outdoors, it is even worse.

最重要的是，狗狗被蚊虫叮咬后，如果不小心传播了带有感染性幼虫血液可能会引发犬心丝虫病。

On top of that when a dog is bitten by a mosquito and accidentally transmits infected larval blood, it can cause heartworms in dogs.

犬心丝虫(又名犬恶丝虫)，呈黄白色细长粉丝状。雄虫长120—160毫米，尾部呈螺旋状卷曲，雌虫长250～300毫米。

心丝虫之成虫寄生于犬猫和人类之右心与肺动脉处，成虫会产下幼虫，（雌虫直接产生幼虫，成为微丝蚴）在血液中循环。

蚤、蚊吸血时把微丝蚴吸人体内，发育成感染性幼虫，进入蚤、蚊的喙内，当蚤、蚊吸血时，幼虫从喙逸出钻人终宿主的皮内，经皮下淋巴液或血液而循环到心脏及大血管内，狗狗由于被含有感染性幼虫的蚊叮咬而遭感染。

The dog heart silk worm (also known as the dog evil silk worm), is yellow and white slender vermicaceous shape. The male is 120 -- 160 mm long, with a spiral tail, while the female is 250 -- 300 mm long.

Adult filarifera parasitize the right heart and pulmonary arteries of dogs, cats and humans. The adult produces larvae, which circulate in the blood.

Fleas and mosquitoes suck microfilar larva inside human body when sucking blood, develop infective larva, enter the beak inside flea, mosquito, when fleas, mosquito sucks blood, larva escapes from the beak inside the skin of the person that drill eventually host, via hypodermic lymphatic fluid or blood and circulation reach heart and big hemal inside, because the dog dog is bitten by the mosquito that contains infective larva and be infected.

心丝虫病前期的症状很不明显，再加上狗狗与生俱来的对疼痛不适的忍耐力，这种疾病就很难被及时发现。

The hertworms can be difficult to detect when the symptoms of the disease are not obvious and when dogs are born with a tolerance for pain and discomfort.

心丝虫如何危害狗狗健康？

How does the heartworms harm dog health?

犬心丝虫病的虫体主要感染狗狗的心脏及肺动脉，当然也有少数会感染犬的胸腔及支气管，从而引起犬的血液循环障碍及呼吸困难直至贫血等症状。

最早出现的症状是慢性咳嗽，但无上呼吸道感染的其他症状，运动时加重，或运动时病犬易疲劳。

随着病情发展，病犬出现心悸亢进，脉细弱并有间歇，心内有杂音。肝区触诊疼痛，肝肿大。胸、腹腔积水，全身浮肿。呼吸困难。

The worm body of canine cardiac filariasis mainly infects the heart and pulmonary artery of the dog, and of course there are a few cases that will infect the chest cavity and bronchus of the dog, causing the blood circulation disorder and dyspnea of the dog until anemia and other symptoms.

The first symptom is chronic cough, but no other symptom of respiratory tract infection, aggravation during exercise, or fatigue during exercise.

With the development of the disease, the dog palpitation hyperactivity, pulse and intermittent, there are murmurs in the heart. Palpation pain, hepatomegaly. Chest and abdominal fluid, edema of the whole body. It\'s hard to breathe.

长期受到感染的病例，肺源性心脏病十分明显。

末期，由于全身衰弱或运动时虚脱而死亡。

病犬常伴发结节性皮肤病，以瘙痒和倾向破溃的多发性灶状结节为特征。皮肤结节为血管中心的化脓性肉芽肿炎症．在化脓性肉芽肿周嗣的血管内常见有微丝蚴。

Pulmonary heart disease is evident in long - term infections.

At the end, death due to general weakness or exhaustion during exercise.

Nodular skin disease is often associated with diseased dogs, characterized by pruritus and multiple focal nodules prone to rupture. The skin nodules are purulent granulomatous inflammation of the vascular center. Microfilar larva is common in the blood vessels of patients with suppurative granuloma.

狗狗在被蚊虫叮咬后的前2个月里，心丝虫只是在皮肤或肌肉里寄生，此时狗狗几乎不会有任何症状。

小半年后也就是到了秋冬季才开始逐渐出现咳嗽、气喘等症状，但此时易与秋冬季的感冒混淆而耽误检查和治疗，狗狗体质强运气好的话可以扛到第二年第三年，但随着体长20多cm的心丝虫及其尸体在心脏里越积越多，狗狗的症状也就越来越严重。

For the first two months after a mosquito bite, hearthworm parasites live only in the skin or muscles.

Less than half year, that is, in the fall and winter began to gradually appear the symptom such as cough, asthma, but it is easily confused with autumn and winter cold and delay the examination and treatment, the dog can carry to strong physique with luck in the second year in the third year, but with more than 20 cm long heart silk worm and its body is piling up in the heart, the symptoms of a dog is more and more serious.

02

如何确诊狗狗体内是否有心丝虫？

How to determine whether a dog has a heart silk worm?

目前市面上有快速检测试剂盒，如果试剂盒检测结果为阳性，就需要抽取狗狗的血液做显微镜检是否有微丝蚴的存在，通过微丝蚴的数量辅助了解心丝虫病的发病程度，成虫的可能感染虫数。

当然，由于心丝虫生活周期的特点，6个月以下的幼犬血液中是观察不到微丝蚴的。除此之外，胸腔X光、心脏B超、心电图都可以辅助判断病情。

There are currently rapid test kits on the market, which are needed if the test results are positive

Blood samples from dogs were collected for microscopic examination for the presence of microfilariasis. The incidence of filariasis and the number of possible infections of adults were determined by the number of microfilariasis. In addition, chest X - ray, heart B - mode ultrasound, electrocardiogram can help judge the condition.

在发现的早、情况还不是特别糟糕的情况下，唯一经美国FDA认可能够杀死心丝虫成虫的药物是美拉索明(经验与实践中，伊维菌素、强力霉素也有一定的作用) ，整个治疗周期至少要三个月，且必须限制狗狗的活动范围，所以预防心丝虫病的意义远大于治疗。

Found in the early, the situation is not particularly bad cases, the only approved by the FDA to kill heart silk worm worm drugs is beautiful pull SuoMing (experience and practice, ivermectin, doxycycline also have certain effect), the treatment cycle at least three months, and must limit the activities of the dog, so the significance of prevention of heart disease than treatment.

03

狗狗按时驱虫为什么还会得心丝虫病？

Why do dogs get heart silk worm?

因为绝大多数的驱虫药并不具备驱除微丝蚴的功能，所以如果你的所在地蚊虫比较猖獗，且流浪狗比较多，请选择含有伊维菌素的驱虫药比如犬心保，即使被蚊虫叮咬，也能够把微丝蚴杀灭在皮肤或肌肉里，避免发育成成虫聚集在心脏严重危害狗狗健康。

Because the vast majority of deworming drugs does not have the function that dispels the microfilariae, so if your local mosquito is more rampant, and the stray dog is more, please select contains ivermectin deworming drugs such as canine heart, even if mosquito bites, can put the microfilariae kill in the skin and muscle, avoid develop into adult gathered in the heart which cause serious damage to a dog\'s health.

04

人类被蚊子叮咬后会得心丝虫病吗？

Can human get heart filariasis after be bitten by mosquito?

不要紧张，这个虫虫通常并不会对人体造成多大影响。虽然心丝虫的微丝蚴可以由蚊子的叮咬进入人类体内，但其并不会在人体内寄生和发育成成虫，只是偶尔会寄生在皮下、肌肉、肺部、体腔等部位形成包埋的结节肿块，造成器官小小的组织机能障碍。

Don\'t be nervous. This bug doesn\'t usually do much to humans. Although the microfilaria of trichinaria can be bitten by mosquitoes and enter the human body, it does not parasitize or develop into an adult in the human body, but occasionally forms embedded nodules and masses in subcutaneous, muscle, lung, body cavity and other parts, causing small tissue dysfunction of organs.

预防犬心丝虫病，除了定期给狗狗进行预防性药物治疗，还应注意防蚊虫叮咬。一旦发现狗狗出现咳嗽、呼吸困难等症状，应及时就医，以免病情恶化。爱护狗狗，让它们健康快乐地陪伴我们。
